Merge branch 'branch-0.9-tres' of github.com:tresata/spark into branch-0.9-tres
Revert "increase memory for sbt otherwise tests fail"
Instead of increasing memory use java 7 for tests but publish compiled with java 6
This reverts commit 425cddf8397363e7e177a2be98d397d054e45ed7.
use hardcoded java 7 for now (java 6 has permgen memory issues with sbt for spark)
merge from branch-0.9-tres
